ABSTRACT:
A driving system for driving a stepping motor to which the number of driving steps and a driving trigger are input to rotate the stepping motor by a half step so as to follow a one-two phase energization sequence. The system energizes one phase of the motor by a driving mode command to position a rotor, and the motor is then rotated by starting energization from two phases next to the one phase already energized.
